Hello, I have Alienware Alpha R2 (aka steam machine) with specification:
GPU: R9 m470X (2GB) - Sea Islands model
CPU: I3-6100T (2c/4t)
8 GB RAM
So i switched from Radeon driver to amdgpu using this command radeon.cik_support=0 amdgpu.cik_support=1
due to Vulkan support.
(source: https://forum.batocera.org/d/7491-enable-opengl-46-and-vulkan-for-an-old-radeon-video-card)
and seems like sound from HDMI stopped working, I don’t know that the issue, because when i switch back to radeon drivers - audio works fine, but Vulkan missing, which is critical for me…
I tried somehow play with Kodi (different outputs, passthrough…) i tried different combinations in audio setting / profile - nothing.
Just to mention sound via BT speaker works fine, there is just a problem with HDMI output.
Any help? Did I miss something? Thank you.
